Just as you wouldn't want to invite certain kinds of people into your home, so it's the same with dogs.

I wouldn't like to share my living room with a psychopath, a paedophile, a racist, a murderer, a thug, or a thief because of their potential to hurt, of fend or do me harm. The same goes for potentially vicious dogs who, if the mood takes them, could easily kill.

Yet again this week another child has been savaged to death by a so-called "pet".

Why are so many people so stupid and blind when it comes to being careful about animals?
